T0 all zul/bont it T11/(ty concern:

Be it known that we, I-IAMiLToN JOHNSON and Asi-1B un A. NoYns, citizens of the United States, residing at Los Angeles, in the county of Lbs Angeles, State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following' is a specification.

Our invention relates to a burner designed to burn very light crude petroleum and distillate produced from petroleum without the use of steam; and the object thereof is to produce a simple and efficient burner for that purpose. We accomplish this object by the burner described herein and illustrated in the accompanying drawings, in which- Figure l is a vertical central section of our burner and a fragment of a heating-stove. Fig. 2 is a plan of the starting-pan.

In the drawings, A is the fuel-cup in which the liquid fuel is generated into vapor. This cup is provided with a central draft-tube B, which extends both above and below the top and bottom thereof. In the Lipper interior surface of this cup is a ledge A', which supports the legs O of the cover O, which is held thereby elevated above the top of the fuel-cup to provide an outlet or port D for the cornbined vapor and air to pass out of the generating-chamber E, which chamber is formed by the cup and cover. There are preferably four of these legs equidistant from each other, and the cover is preferably concave, as shown. To the bottom of the central draft-tube is affixed a funnel-mouthed air-tube F for the better directing of the air into the central drafttube. The top of the cover is provided with a lug O", having' a hole extending therethrough for convenience in handling.

Surrounding the draft-nue a short distance below the fuel-cu p is a starting-cup G, which preferably consists of concentric channels a and connected by channels c of less depth than channels a and I). Between channels a, and c are air-inlets CZ, which admit air for combustion, being particularly useful when starting a lire. Any other form of startingcup may be used; but we prefer this form, as the generation of liquid fuel into vapor is very quickly effected by reason of the large surface of burning fuel and the ready access thereto of air for combustion. The liquid fuel is supplied into the fuel-cup by pipe H, connected to a suitable supply. (Not shown.)

In the operation of our burner it is placed in the combustion-chamber of a furnace, stove, or other structure. We have illustrated it as placed in the combustion-chamber of a stove I, having grate-bars J and ash-pit K, with the starting-cu p resting on the grate-bars. The liquid fuel is permitted to fill the fuel-cup and to iiow out and lill channel a up to channel c, when it is eut ofi', and the fuel in the channel is lighted, and before it is all burned up the vapor is generated and passes out of port D and burns in a clear blue flame all around the top of the fuel-cup. At the same time air passes up through the central draft-tube and commingles with the vapor, and thereby aids combustion. Before the fuel in the cup is all vaporized the necessary supply to keep up the fire is permitted to flow into the cup. As it isinipossible to exactly gage the amount of fuel necessary to start the fire, usually an amount in excess is permitted to fiow out of the fuel-cup. `This excess runs into channel Z) and is burned therefrom.

It will be observed that by this construction a retort-chamber is formed which is provided With a draft-tube, which brings air into the chamber to commingle with the vapor before either is fed to the flame. It is also manifest that other forms may be adapted for the retort without departing from the spirit of our invention, which consists, essentially, in

'a retort-chamber into which air is drawn to coinrningle with the vapor of the liquid fuel and then be discharged therefrom to feed the flame.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is- A l. Ahydrocarbon-burnercomprisingafuelcup, the upper free edge of which is thickened, a ledge formed in the thickened portion ofthe cup, acap, legs formed on the lower free edge thereof and resting upon the ledge, a draft-Hue and an oil-supply pipe projecting' into the cup and means for heating the cup and cap.

2. A hydrocarbon-burner comprising a vaporiZing-chaniber, a draft-Hue and an oil-supply pipe projecting into the chamber, a starting-cup located beneath the chamber,the starting-cup provided with concentric channels and connecting radial channels of less depth than the concentric channels.

3. Ahydrocarbon-burnercomprisingafuelcup and cap therefor, a draft-fine projecting through the fuel-cup and extending some distance therebelow, a starting-cup received upon the draft-line beneath the fuel-cup, the starting-cup resting upon a grate below which the draft-Hue projects and an air-tube removably secured to the projecting portion of the Vitnesses:
